ObjectiveTo analyze the causes of discomfort occurring in the interventional treatment of diabetic foot, to discuss the individualized nursing measures for improving the patient's comfort and cooperation,and for increasing the successful rate of the interventional procedure.MethodsThe control group included 9 patients who received conventional nursing care.The study group had 13 patients who accepted individualized nursing care and nursing intervention, which was designed according to every patient's individual conditions. ResultsIn the control group, one patient could not endure the surgery to the end because of the long operating time. Another two patients had to take examinations repeatedly because the imaging quality was very poor,which was caused by the body movement due to uncomfortable mechanical stimulation.Urinary retention occurred in one patient.The mean operative time of the control group was 2.8 hour per surgery.The average dosage of contrast medium used was 150 -300 ml per procedure.All the subjects in the study group completed the surgery successfully,the mean operative time was 2.2 hour per surgery and the average dosage of contrast medium used was 100 -200 ml per procedure.Conclusion During the perioperative period of interventional treatment for diabetic foot, the effective individualized nursing care and nursing intervention,the measures to improve patient's comfort and the cooperation,etc. can certainly increase the successful rate,saving the operating time and reducing the contrast dosage.

Retinoblastoma(RB)is the most common intraocular malignancy of children with extremely poor prognosis. MicroRNAs are small non-coding single-stranded RNAs in eukaryotic cells, which regulate the expression of gene by mRNA degradation or translation inhibition. MicroRNAs, acting as oncogenes or tumor suppressor genes, are associated with the occurrence and development of RB directly, which is vital for the early diagnosis and clinical targeted therapy of RB. This review summarized the expression of microRNAs in RB and the related mechanism.

Objective To study the protective effect of total flavones of hawthorn leaf (TFHL) on renal ischemia/reperfusion (I/R) in rats.Methods A model of renal I/R was made by clamping double renal pedical for 60 min and reperfusion for 24 h.TFHL (30 or 60 mg/kg) was injected before clamping renal ischemia. The level of serum urea nitrogen(BUN), serum creatinine(Scr), tumor necrosis factor-?(TNF-?),interleukin-1(IL-1) in serum were detected after reperfusion for 1 and 24 h,respectively,and the level of malonaldehyde (MDA) and erythrocuprein (SOD) in renal tissues were measured after reperfusion for 24 h.Results TFHL significantly decreased the level of BUN and Scr, decreased the concentration of TNF-? and IL-1 in serum. Pretreatment with TFHL also enhanced the activity of SOD reduced the concentration of MDA in renal after I/R.Conclusions TFHL has significantly protective effect on renal I/R and markedly improve the renal function. The mec-hanisms are associated with decreasing the lipid peroxidation reaction and reducing the level of TNF-? and IL-1.

?AIM:To observe the values and changing rules of angle Kappa in corneal refractive surgery under light and dark conditions.?METHODS:Two hundred and thirty-four eyes of 118 patients for corneal refractive surgery were enrolled for this study.Pupil diameters and angle Kappa values under light and dark conditions were measured by Keratron Scout corneal topography.?RESULTS: There were significant differences in pupil diameters between light and dark conditions (P<0.01). More angle Kappa of both eyes distributed in the superior nasal quadrant under light conditions, and more angle Kappa distributed in the superior temporal quadrant under dark conditions.The differences of horizontal and vertical offsets of angle Kappa under two conditions were statistically significant (P<0.01).?CONCLUSION: The changes of pupil diameters in light and dark conditions could affect angle Kappa and then affect the accuracy of corneal refractive surgery centered on angle Kappa.

Objective To study the interobserver variabilities and the differential diagnosis value of Breast Imaging Reporting and Data System-Ultrasound (BI-RADS-US) lexicon for small ( ≤ 2 cm) breast nodules. Methods Between January 2009 and December 2011, 289 patients with small (≤2 cm) breast nodules (n=317) were included. According to sizes, the lesions were divided into two groups, i.e., 0-1 cm (n=160) group and 1-2 cm (n=157)group. Each lesion was described independently by 3 radiologists using BI-RADS-US lexicon. Interobserver variabilities were assessed by Kappa test. Chi-square test was used to compare the frequency difference of the descriptors between malignant and benign lesions. Sensitivity, speciifcity, accuracy, positive predictive value and negtive predictive value were calculated. Results (1)Moderate agreements were obtained for lesion shape, orientation, margin, echo pattern, surrounding tissue and calciifcations (κ=0.44, 0.57, 0.48, 0.43, 0.51 and 0.57) in 0-1 cm group. Substantial agreements were obtained for lesion shape, orientation, margin and echo pattern (κ=0.65, 0.61, 0.64 and 0.63) in 1-2 cm group. (2)Irregular shape, non-parallel orientation, non-circumscribed margin, echogenic halo and microcalciifcations were more frequently found in malignant nodules than in benign nodules in 0-1 cm group [52.3% (34/65) vs 20.0% (19/95), 38.5%(25/65) vs 13.7%(13/95), 75.4%(49/65) vs 32.6%(31/95), 18.6%(12/65) vs 0 (0/95) and 10.8%(7/65) vs 2.1%(2/95);χ2=18.19, 13.08, 28.22, 16.39 and 3.95;P=0.000, 0.000, 0.000, 0.000 and 0.047]. Similarly, irregular shape, non-parallel orientation, non-circumscribed margin, echogenic halo, shadowing, changes of Cooper′s ligament and microcalciifcations were signiifcantly more frequent found in malignant nodules than in benign nodules in 1-2 cm group [74.2%(49/66) vs 12.1%(11/91), 36.3%(24/66) vs 5.5%(5/91), 93.9%(62/66) vs 22.0%(20/91), 37.9%(25/66) vs 3.3%(3/91), 30.3%(20/66) vs 7.7%(7/91), 15.2%(10/66) vs 0 (0/91) and 16.7%(11/66) vs 4.4%(4/91);χ2=62.59, 24.21, 79.40, 31.22, 13.73, 12.30 and 6.67;P=0.000, 0.000, 0.000, 0.000, 0.000, 0.000 and 0.010]. (3)In both groups, a good sensitivity was demonstrated (75.4%&93.9%) when using the non-circumscribed margin as a criterion for malignancy, and high speciifcity was achieved in two groups (80.0%-100%and 87.9%-100%) when other descriptors including irregular shape, non-parallel orientation, echogenic halo, shadowing, changes of Cooper′s ligament and microcalciifcations were used as differentiation criteria. Conclusions Good interobserver agreement can be achieved using the BI-RADS-US lexicon in the diagnosis of small breast nodules. Non-circumscribed margin are proved as the most valuable sign for screening malignant breast lesions ≤ 2 cm. High speciifcity was found for irregular shape, nonparallel orientation, echogenic halo, shadowing, Cooper′s ligament changes and microcalciifcations, which can help biopsy and preoperative diagnosis.

To study the comparability of myocardial enzyme spectrum detection results by two different bio-chemical testing systems to provide references for mutual accredit of detection results in one lab. Following NC-CLS document EP9-A2, 8 clinical specimens were selected every day for five days and tested for AST, LDH, CK and CK-MB respectively with Siemens ADVIA1800 and Johnson & Johnson Victro350 systems. Acknowledging Siemens AD-VIA1800 as objective testing system, the results were utilized to make correlation analysis and clinical acceptability esti-mation. There was high precision in Siemens ADVIA1800 and Johnson & Johnson Victro350 (CV≤1/3CLIA′88 allowable error). It's proved by t test that the difference of the myocardial enzyme results tested with Siemens ADVIA1800 and Johnson Victro350 was statistically significant (P<0.01), while the two testing systems showed significant correlation (r>0.975). In the comparison with the Siemens ADVIA1800, the standard errors (SE%) of AST, CK and CK-MB tested with Johnson Victro350 were 4.0%-6.6%, 9.6% and 13.3%, which were accepted by clinical standard; while the SE% of LDH tested with Johnson Victro350 were 11.2%-12.7%, which were beyond clinically acceptable range. In case one item is tested by different testing systems in one laboratory, the comparison and bias estimation acceptable eval-uationare necessary to judge the clinical acceptability, which can ensure the accuracy and consistency of the results.
